What is the primary way Lua and C communicate?

They communicate via a virtual stack where C code pushes values for Lua to read, and Lua passes arguments to C functions by placing them on the stack in a specific order.

Does this skill help with memory management?

Yes, it covers essential patterns for managing memory safely when passing data between the Lua garbage collector and native C code, including the use of userdata and metatables.

Can I call Lua functions from within my C program?

Absolutely. This skill provides implementation patterns for loading Lua scripts, retrieving global functions from the Lua state, and executing them with parameters from the C side.

When should I use C instead of pure Lua?

You should use C for performance-critical algorithms, accessing low-level system APIs, or integrating existing C/C++ libraries that aren't natively available in the Lua environment.

API開発

Integrates high-performance C code with Lua scripts using stack-based communication and native data management.

概要

This skill provides expert guidance on the Lua-C API, enabling developers to extend Lua with native C functionality or embed Lua as a scripting engine within C applications. It covers essential topics like virtual stack manipulation, bidirectional function calling, creating C-based modules, and managing custom userdata and metatables. Ideal for performance-critical projects, this skill ensures safe memory management and optimized communication between native code and script environments, allowing for seamless interoperability between high-level logic and low-level performance.
